摘要:

本实验以红富士苹果为材料,研究不同质量浓度的β-氨基丁酸对苹果采后青霉病的防治效果,以及结合质量分数为1.5%的壳聚糖对苹果贮藏品质的影响。结果表明,0.75g/L的β-氨基丁酸对苹果采后青霉病的防治效果最好,并且它对苹果在贮藏期间的呼吸强度、乙烯释放速率、可溶性固形物含量及可滴定酸含量的变化几乎没有影响,并有效抑制了硬度的下降和质量损失率的增加。β-氨基丁酸结合1.5%的壳聚糖溶液后,显著抑制了苹果贮藏期间一些生理指标的变化,保鲜效果明显优于β-氨基丁酸单独处理。

Abstract:

The effect of different concentrations of β-aminobutyric acid on the prevention and control of postharvest blue mold of
Red Fuji apple was studied as well as the impact of β-aminobutyric acid combined with chitosan coating treatment on the storage
quality of apple. Results revealed that 0.75 g/L β-aminobutyric acid was the most effective treatment for the control of postharvest
blue mold while having almost no influence on respiration intensity, ethylene release rate soluble solids or titratable acid content
during storage of Red Fuji apple. However, β-aminobutyric acid treatment effectively delayed the reduction of firmness and
the increase of weight loss rate. β-aminobutyric acid treatment when combined with 1.5% of chitosan coating showed a better
preservative effect , and significantly inhibited changes in several physiological indexes during storage of Red Fuji apple.
